AgTe2Tm
AgTe2Tm is a semiconducting ternary telluride compound being investigated for its potential utility in phase-change memory devices.
About AgTe2Tm
AgTe2Tm is a complex ternary telluride belonging to the class of phase-change memory materials. As a semiconducting compound, it exhibits electronic properties that make it a subject of interest for high-density, non-volatile memory architectures where rapid switching between structural states is required.
Due to its near-hull thermodynamic stability, this material is considered a viable candidate for experimental synthesis and integration into device prototypes. Its structural versatility, evidenced by multiple reported configurations, suggests a flexible lattice capable of supporting the reversible phase transitions essential for modern memory technologies.
Key Properties
Cross-validated computational properties for AgTe2Tm, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the phase-change memory materials class.
Within the broader landscape of phase-change materials like the ubiquitous Ge2Sb2Te5 or the simpler AgTe, AgTe2Tm occupies a specialized niche by incorporating rare-earth thulium into the silver-telluride framework. While traditional binary systems like Ag2Te or Sb2Te3 serve as foundational benchmarks for phase-change behavior, the addition of thulium in AgTe2Tm provides a distinct chemical pathway to tune the electronic and structural characteristics of the material compared to established siblings such as AgSbTe2.
